AUTOGRAPHIC REGISTER.

Specification of Letters Patent.

Patented Aug. 2a, 1915.

Application filed November 2, 1914. Serial No. 869,730.

T 0 all whom it may concern Be'it known that I, THEODORE F. SGHIR- thefollowing is a full, clear, and exact desoription, reference being hadto the accompanying drawings, forming part of this specification.

The invention has relation to autographic registers of the pull outtype, the principal features of which are a means for supplying severalwebs of paper to a tablet plate upon which writing is to be done, atension device at the end of the tablet to hold. the paper firm whilewriting on it and while pulling it out over the tablet, and a tearingblade adapted to form an edge against which the pulled out papers may betorn off.

In resigter of such type, it is customary in the art to provide somemeansof locking both the tension plate and tearing blade out ofoperative position in contact with the body of the device, so that theWebs of paper can be threadedunder the tension plate for restocking themachine.

The object of my invention is to provide, in a simple and inexpensiveway, such a locking means, and it is accomplished by that certainstructure and arrangement of parts to be hereinafter specificallypointed out and claimed.

In the drawings, Figure 1 is a side elevation of the front portion of anautographic register, showing the tearing blade in contact postion. Fig.2 is a top plan view of the same, with the blade broken away at one endto show the tension plate. Fig. 3 is a side elevation of the blade andtension plate on a larger scale with parts broken away, showing theblade raised from tearing position, and the tension'plate raised out ofcontact with the tablet plate, and bothlocked in such positions Fig. 4is an end elevation of the register taken at the pull out end, with theparts raised and locked.

The register shown has a casing 1, in which provision is made in anydesired manner for the rolls of paper 2. The paper is brought up overthe tablet plate 3 at the top of the casing, and when in use strips ofmanifolding material are placed between the two webs to make theduplicate copies.

At the pull out end of the register, that is to say, the end over whichthe webs of paper are drawn after entries have been made thereon, islocated the tearing blade 4 and tension plate 5.

The tearing blade is mounted on a pair of arms 6 at each side of thecasing 1, and these arms are rigidly mounted on the spindle 7, whichextends across and is journaled in the sides of the machine. By means ofthe spring 8, coiled around the'spindle 7 and secured at-one end theretoand secured at 9 to the casing, the spindle and hence the arms are undertension and tend to press the blade 4 down against the end of the tabletplate. 7

The tension plate 5 extends across the machine underneath the tearingblade and has small spindles 10, 10 at each end. These spindles aremounted in the slotted lugs 11, 11, formed in the casing of the machine,so as to permit of suflicient movement of the plate, and the plate isnormally springpulled against the tablet plate end by means of the ears12, 12, extending through the tablet plate and secured by springs 13,13, to the casing.

The arms 6, 6, of the tearing blade are mounted on the spindle 7 so asto leave a space between them and the casing of the machine. Pivotallymounted on the casing at 14 is a cam plate 15, which has space enough toswingbetween the blade arms and the casing. The top edge of the cam isso disposed that it lies in contact with the spindle 10 (Fig.3) of thetension blade, and the cam surface is such that when the cam is rockedby its handle 16, it will lift the spindle against its spring tension at13, and thereby lift one end of the tension blade and release thetension.

The handle 16 on the cam plate is so located that when the plate hasbeen shifted to lift the spindle 10, the handle will lie under theextended portion 6. of the raised tearing blade arm. In order to shiftthe cam plate, however, the tearing blade must first be lifted, or thehandle 16 will abut against the arm 6. When the tearing blade is liftedon the other hand, the cam plate may be pushed over so that the handle16 lies under the extension 6 whereupon the webs from the rolls 2,2, arebrought up over the tablet plate, the tension plate and tearing bladeare locked up, as just described, and the webs fed under the tensionplate. The tearing blade is then raised slightly, the cam plate handlereleased there by, so that the cam can be swung back, and the tearingblade allowed to return to tearing position against the tablet plate.Such notation as is desired is made on the exposed paper, slightly sothat the end of the paper can be reached, and the portion desired pulledout over the tablet While still under tension. The bladeis then allowedto descend and the paper torn ofi at its edge. 1

It will be noted that the tearing blade may be swung back as far asdesired without affecting the tension plate'in any way.

In devices where the tearing blade raises the tension plate,'either thetension is constantly being released at the wrong time or else theremust be provided some kind of a lock to prevent the blade from beingraised normally beyond a certain point. The

spring tension on tearing blades in such machines has to bevconsiderable and it is not desirable to open the operator to the risk ofhaving it shut down on his fingers when filling the machine. The devicenow shown is particularly free from this danger, as the tearing blademust be moved positively and thus come under control of the operator,be-

fore the cam can be released to lower the tension plate.

It is not desired to be limited in the claims that follow to suchdetails of construction now particularly pointed out, as the mechanicalequivalent thereof would as well fit the reading of the claims. It isbelieved that the structure is now fully and clearly specified, and thatthe principal object in providing for independent control of tensionplate and tearing blade in connection with a locking means for both isnow apparent. 4

Having thus described my invention, what the tearing blade raised Iclaim as new and desire to secure by Letters Patent, is

1. In an autographic .register having a tablet for supporting a papersupply, a tension device to hold the paper, and a tearing blade, meansindependent of the tearing blade for raising the tension device, andmeans on the raising means to hold the tearing blade out of operativeposition.

2. In an autographic register having a tablet for supporting a papersupply,-=a tension device to hold the paper, and a tearing blade, a camplate independent er the tearing blade for raising the tension device,and means on the cam plate to hold the tearing blade out of operativeposition. v

3. In an autographic register having a tearing" blade, and a tension.device,-a means 3 for raising the tearing blade, an independent meansfor raising the tension device, and

means "on the latter means lying in the path of the former means, andpositioned so that the tearing blade must first be raised, to

allow the tension device to be raised, and so that the tearing bladecannot be lowered until the tension device islowered, for the purposedescribed. 7

{L111 an autographic register. having a tearing blade and a tensiondevice, arms for,

raising the tearing blade, a pivoted plate independent of said arms forraising the ten sion device, a contact means on the pivoted platepositioned in the path of the tearing blade, arms to prevent, movementof the plate from normal position without raising of the arms out of theway, and to prevent.
